I have been using the M tape for several years now. I like a lot of qualities of the tape, but often have rolls that end up with a very tight unwind half way through the roll. Worse when the tape is "older" but even on cases that are just a couple months old. Also with the current case, I have had a few rolls with thin patches, where you can see through the tape. Those are usually only about a foot long, then go back to a normal good roll of tape. I do wish mueller would improve the quality control.
When its a good roll - it is great tape. When its a bad roll- its frustrating.
